Professional Dehumidifier 35 L/24h

OKLIMA DR35 - Professional Stackable Dehumidifier

The Oklima DR 35 dehumidifier line is a high quality, robust and reliable machine designed to control humidity in indoor environments. Furthermore, the Biemmedue Oklima DR 35 dehumidifier is ideal for dehumidifying dry areas, residential areas, archives and storage centers, and for drying following floods and water damage.

The Oklima DR 35 dehumidifier is capable of extracting 37 L of condensation water in 24 hours in ambient conditions of 32°C with 90% relative humidity.

Oklima DR dehumidifiers provide significant energy and consequently economic savings thanks to their advanced electronic control that allows you to adjust the operation of the machine without waste based on the needs of the environment in which it is located. This is also allowed by the presence of a built-in thermo-hygrostat that automatically detects the temperature of the environment and indicates to the dehumidifier the dehumidification levels to maintain.

The Refrigerant Gas that Biemmedue Oklima DR professional dehumidifiers are equipped with are of the R454C type, that is, they contain very low GWP values which refers to the impact that the gas in question has on global warming. The use of gas with high GWP will be gradually banned in the future to reduce emissions that contribute to global warming, consequently it is useful to immediately equip oneself with dehumidifiers that use this type of gas in order to avoid having to replace them prematurely in the future.

In particular, the Oklima DR 35 Professional Dehumidifier allows you to easily remove the tray and connect the condensation extraction pump kit that can be purchased separately, which allows you to pump the condensed water to a higher level than the room in which the dehumidifier is installed. The maximum head is 5 meters.

How to choose your dehumidifier

When choosing your Biemmedue Oklima Professional Dehumidifier, it is essential to observe the dehumidification capacity expressed in liters over 24 hours (L/24h). This value indicates how much water the Biemmedue Dehumidifier in question is able to extract from the humidity in the environment in which it is located. Dehumidifiers with high capacities can work in large spaces and dry in less time in small spaces . On the contrary, dehumidifiers with low dehumidification capacities can work better in smaller environments that may not require overly powerful machines.

It is also essential to observe the required air flow, that is, how much air the machine is able to remove in an hour to properly treat the environment in which it operates.

In the case of the Oklima DR 35 dehumidifier in question, this is suitable for environments with volumes from 100 m³ to 200 m³ .

Electronic control

The models of the Biemmedue Oklima DR line are equipped with an electronic humidistat and modern electronic control that together allow you to optimize the use of the dehumidifier by turning it on only when necessary. Furthermore, thanks to the soft touch display it is equipped with, you can personally set the humidity levels you want to maintain in the work environment.

During operation, the electronic control displays the current humidity and temperature values in the room, to ensure control over the climate data of the surrounding environment .

Furthermore, the electronic control manages two hour counters : one resettable and one cumulative, essential and practical for rental.

How it works

Biemmedue dehumidifiers are autonomous devices that do not require installation to function but simply work by connecting them with a plug to the electrical network. The professional dehumidifier in question consists of a closed circuit that contains ecological refrigerant liquid, a compressor, a condenser, a capillary tube, an evaporator and a fan.

Biemmedue dehumidifiers are autonomous devices, operating without the need for installation, simply by connecting them to the electrical network with a plug.
The dehumidifier consists of a closed circuit containing an ecological refrigerant fluid, having the following main elements:

• compressor (n°2) : determines the circulation of the refrigerant fluid
• condenser (n°3 ): in this element, physically similar to the car radiator, the fluid in the gaseous state, pushed by the compressor, transforms into liquid, giving off heat; this heat warms the condenser itself
• capillary tube (n°5 ): in this element the fluid, having become liquid, expands by reducing its own pressure
• evaporator (n°6) : in this element, which is also made up of a battery similar to a car radiator, the liquid is transformed into gas, removing heat and consequently cooling the evaporator. The refrigerant fluid, once again a gas, continues its journey through the compressor and the cycle begins again.
  The air to be dehumidified is pushed through the dehumidifier by a fan (n°1) first passing through the evaporator (cold) and then the condenser (hot).
  The operating cycle is therefore as follows:
• The air passes over the surface of the evaporator, where it cools, depositing excess humidity, which turns into water droplets that fall into the collection tray.
• Subsequently, the air passes through the condenser, where it regains a few degrees of temperature and is reintroduced into the environment drier and warmer, thus contributing, in the mix that is determined over time, to lowering the humidity level of the environment, until the desired values are reached.

When the ambient temperature is below certain values (15°/18°C) , the temperature of the evaporator surfaces drops in turn, causing ice to form which limits the passage of air, compromising the proper functioning of the system.

To overcome this possible inconvenience, the automatic defrosting function is provided, which consists in the possibility of heating the evaporator when the probe detects temperatures that are too low.
In this case, through a by-pass valve (n°4) , the compressor directly introduces the gas into the evaporator, without passing through the condenser, causing an increase in temperature.
The by-pass circuit closes automatically when the probe detects a higher temperature and the dehumidification cycle resumes normally.

It is important to note that this defrosting system guarantees the return to perfect efficiency of the dehumidifier after a few seconds; furthermore, it is the only defrosting system that allows full efficiency of the dehumidifier even with very low temperatures of the air to be dehumidified (lower than 8/10 °C).
